With poweroff... it turns off the computer, right now. That's it.
With shutdown, you can halt the computer, you can shutdown, you can reboot, you can notify any logged user that you are shutting down, and you "schedule" the shutdown, for example 1 minute or 5 minutes after notifying the users the system is shutting down.

$ sudo shutdown -h now(as regular user, must give that user's password)
or
# shutdown -h now(as superuser)
Whenever you see messages like that, the operation you're trying to perform needs to be done with elevated permissions. So, be careful and know what the operation is going to do before moving further. You can always search online and in the man pages to find out what a command does - and, if you can't find anything on your own, you can always ask for help.
I tried my best i can't solved it please help me
In a terminal,
Code:
sudo halt -pSystem commands need to use sudo, or the root account.
These, or similar messages, are what you'll get when your account doesn't have permission to perform the activity. I was just expanding on this, making sure you know that this is true for some other operations.
As others have said, use
sudo.For example:
sudo shutdown -h nowIt will then ask you for your password. Type your password. If nothing appears on your screen as you type your password, that's expected behavior. Just type your password and press the enter button.
Only use 'sudo' when you absolutely need to use sudo. Using sudo is basically running the command as an administrator. It can and will bite you in the butt.
